Question: In this experiment we will investigate how the moisture of the soil affects the growth of the Viola tricolor. Hypothesis: The soil that is closer to the nearest water has more moisture, meaning that the Viola tricolor that grow there have more access to water which leads me to …

1. The Kingdom Protista consists of organisms that are eukaryotic, which are organisms whose cells have nuclei and membrane-enclosed organelles. Members of the Kingdom Protista are known as protists. Protists are defined as unicellular, or single-celled, eukaryotic organisms. However, some protists are multicellular. Many protists live individually, but some are …

Problem: What effect will a change in temperature of hydrogen peroxide (C) have on the activity of the enzyme Catalase in potatoes measured by the height of the bubbles created by the reaction in a test tube? Hypothesis: All enzymes either breakdowns substances and\or they put substances together. An enzyme …

Aim: Finding the isotonic point of potato cells by testing it in different concentrations of salt water. This diagram shows the movement of water through hypotonic, hypertonic and isotonic. But what are the arrangements of molecule for them? This is shown on this simple diagram. Hypothesis: I believe the isotonic …

Introduction Enzymatic browning is a biochemical process in which plant (fruit or vegetable) tissues take on a brown color when exposed to oxygen. This experiment was conducted to test the affect temperature on the rate of browning of a Malus domestica or more commonly known as the Fuji apple, immersed …

Introduction In this experiment we will be focusing on the factors, which influence the process of germination of a plant. Germination is the process when a seed sprouts from dormancy. The seeds are placed in soil or in any type of wet paper towel. It is basically the development of …

Variables involved: Different pH levels will affect the Catalase enzyme by determining whether the enzyme activity will increase, decrease or if it will denature altogether, so the pH level of the Hydrogen Peroxide, which Catalase breaks down into oxygen and water, will be our independent variable. The temperature of the …

Hypothesis: The DNA extracted from the strawberry will be the greatest amount due to their softness and pulverization. They have large genomes being an octoploid. This means that they have eight of each type of chromosome in each cell. Thus, the strawberry should provide the most DNA. Procedure: I used …

Hypothesis:- Due to automobile movement on Sohna Road the texture, ph and the water content of soil maybe different. The soil samples are taken 1 metre, 2 metre and 3 metre from the road. According to me the texture, ph and the water content will be different because the soil …

1. Aim To investigate the amount of protein present in different types of milk by measuring the mass of protein in each types of milk. 2. Introduction Casein is a protein which is found in milk. This is a conjugated protein that has prosthetic groups that is called phosphoric acid, …
